Looking to see whether any stats help your ‘thoughts’.
On the ‘too often’: the outlier example might be Siffert who raced ‘a lot’ in 2025 - after a stellar 2024 (9 races, 4 x #1s, 5 x #2s) 2025 didn’t go well. Coach advice?
You put out Philipp as an example of “limiting your racing to 2 big races per year [as] optimal at least for longevity”. But in 2025 she raced three fulls, the same ones as this year’s plan. When not affected by the pandemic or injury she typically races 6 times including recently two or three fulls. Was boosted to total 9 races by $$ T100 extras in 2024. Counter to your hypothesis, though, the year Philipp raced 9 she won IMWC! (?“Eye on the Prize?” “LP only raced 4x last year” and she underperformed (against her champion standard) at Kona. This year: we’ll see.
Sticking to two fulls seems reasonable but either the Pro Series, these last two years, or the need to KQ and the wish to race Roth means many top athletes choose to race three each year. This was eased, for post pandemic years, by previous champions not needing to validate. Laidlow races rarely but last year: 3 fulls; this year 3 fulls. KQ/validation, Roth and then IMWC. Maybe Matthews’ unfixable tyre and no suitable neutral wheel Texas fiasco was a blessing in disguise: IMNZ, Roth and then Kona, as opposed to 3 then Kona.
A fair few are affected by injuries/illness (most likely not caused by too many races) which skew the figures.
Athlete then fulls raced 2025, 2024, 2023, 2019, 2018, then apparent 2026 plan:
LCB 2,1,1,3,3 - 2
Loevseth 3(debut) - 3
Matthews 3,3,2,1(debut) - 3
Philipp 3,2,1,1,1(debut) - 3
Christensen 3,5,3(debut) - 3
[Knibb, Sodaro** (MiA/rehab/thinking about Kona validation), Derron are all ‘special cases’ imho.]
